I have 1992 Cadillac Deville. Recently had old Freon removed

Customer Question

I have 1992 Cadillac Deville. Recently had old Freon removed and all new Freon (34a) put in and computer adjustments made. A/C was working perfect and 1.5 hours into a trip on very hot and humid day, 'A/C Requires Maintenance' light went on and A/C started pushing out hot air only. Shut it down and parked it. Next day, when doing local driving I felt cold air coming from foot area and realized I had not shut A/C off completely. Turned A/C to 'High' and it has been working ok since. Concerned that it will stop working again. Any idea what could have caused problem and how to make sure it doesn't happen again ? This is going to be our Florida winter car and need A/C to be VERY dependable.

Now that I know where the problem generally lies, I will take it to a Caddy dealer and have it taken care of. I have an appointment set up for tomorrow am. I was concerned it could be something worse like the compressor. Thanks for the help.
